Graphics performance in The Supernauts
summary
Supernauts runs on Unity 4 with a shared C# client/server codebase and a 20‑person studio; the client receives voxel blocks from the server and converts them to renderable meshes using bitmaps packed as bitmasks (shifted/AND/OR across axes plus three face bitmaps), incremental mesh updates and vertex deduping. Smoothness uses a modified Catmull‑Clark without subdivision plus a volume‑preserving push along face normals. Ambient occlusion is computed per‑vertex by projecting nearby faces onto a hemisphere (per‑vertex ambient occlusion via hemisphere projection). Static mesh combining replaces costly dynamic batching; systems are tuned for mobile (iPad) and ship in working form.
